Question

11 The net force on a vehicle that is accelerating at a rate of 1.5 m/s² is 2,800 newtons. What is

the mass of the vehicle to the nearest kilogram?

Answer 1

`Mass = 1867kg`

Explanation:

Given

`Force = 2800N`

`Acceleration = 1.5m/s^2`

Required

Determine the mass of the vehicle

This question will be answered using Newton's second law

`Force = Mass * Acceleration`

Substitute values for Force and Acceleration

`2800 = Mass * 1.5m/s^2`

Make Mass the subject

`Mass = (2800N)/(1.5m/s^2)`

`Mass = 1866.6667kg`

`Mass = 1867kg` ---- approximated

Hence, the mass of the vehicle is 1867kg
